某SUV低速横摆问题的识别分析
|
摘要
在某SUV样车2挡加速过程中,当发动机转速为2 000~2 600 r/min时存在明显的车身横摆现象,严重影响乘坐舒适性。通过对道路上的车内驾驶员座椅导轨进行振动测试,采用频谱分析、阶次分析、对比分析等方法对低速车身横摆产生的原因进行了研究,确定该车身横摆是由驱动轴布置角度大、万向节轴向派生力大引起的。经过控制内球笼滑道与三球销配合间隙和换用润滑效果更好的润滑脂,降低了万向节轴向派生力。改进后,道路试验结果和主观评价结果均表明车身横摆得到明显改善,对低速车身横摆问题的排查和解决有一定参考作用。
The problem of body frame shimmy occurred at engine speeds of 2 000 r/min to 2 600 r/min for a certain SUV in second gear acceleration, and it seriously affected the ride comfort for passengers.The low speed shimmy was studied by the methods including the vibration test of the driver's seat guide rail, spectral analysis, order analysis and comparative analysis.It was found that the shimmy problem was caused by a large drive shaft arrangement angle and the large universal joint axial force. By adjusting the clearance between the inner ball cage slide and the tripod and by using better lubricating grease, the universal joint axial force decreased. With these improvements, the road test and subjective evaluation show that the vehicle shimmy motion was extremely reduced.
